在供配電(dian)技術里的存在有雙(shuang)電(dian)源和(he)雙(shuang)回(hui)(hui)路，那什(shen)(shen)么(me)是雙(shuang)電(dian)源，什(shen)(shen)么(me)是雙(shuang)回(hui)(hui)路，有什(shen)(shen)么(me)作用(yong)，兩者之間的關系是什(shen)(shen)么(me)？

①雙(shuang)電(dian)(dian)(dian)源(yuan)是(shi)指(zhi)相(xiang)(xiang)(xiang)對(dui)(dui)互相(xiang)(xiang)(xiang)獨(du)立的(de)兩個電(dian)(dian)(dian)源(yuan)。對(dui)(dui)負荷(he)用(yong)戶或(huo)(huo)負荷(he)設備(bei)而言所(suo)謂的(de)雙(shuang)電(dian)(dian)(dian)源(yuan)包含著兩層意思：一(yi)是(shi)雙(shuang)電(dian)(dian)(dian)源(yuan)，二是(shi)回(hui)路（可能距(ju)離會(hui)很短，例(li)如自帶蓄電(dian)(dian)(dian)池(chi)的(de)應急燈）；它(ta)既(ji)強(qiang)(qiang)調(diao)兩個電(dian)(dian)(dian)源(yuan)的(de)互相(xiang)(xiang)(xiang)備(bei)用(yong)或(huo)(huo)一(yi)用(yong)一(yi)備(bei)，又強(qiang)(qiang)調(diao)兩回(hui)線(xian)路的(de)互相(xiang)(xiang)(xiang)備(bei)用(yong)或(huo)(huo)一(yi)用(yong)一(yi)備(bei)。②雙(shuang)回(hui)路則只(zhi)(zhi)是(shi)指(zhi)兩回(hui)線(xian)路，它(ta)只(zhi)(zhi)強(qiang)(qiang)調(diao)供配電(dian)(dian)(dian)線(xian)路的(de)互相(xiang)(xiang)(xiang)備(bei)用(yong)或(huo)(huo)一(yi)用(yong)一(yi)備(bei)，它(ta)對(dui)(dui)電(dian)(dian)(dian)源(yuan)無要求，即(ji)指(zhi)此雙(shuang)回(hui)路可以(yi)由(you)一(yi)個公共的(de)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)，也可以(yi)由(you)兩個不同的(de)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)。

明泰(tai)(tai)電(dian)(dian)(dian)氣（蘇(su)州）有限公司是正泰(tai)(tai)集(ji)團在(zai)蘇(su)州地區一家(jia)授(shou)權(quan)的(de)經(jing)銷(xiao)(xiao)(xiao)企業，連續十(shi)年銷(xiao)(xiao)(xiao)量居(ju)正泰(tai)(tai)營(ying)銷(xiao)(xiao)(xiao)網絡(luo)名，PC雙電(dian)(dian)(dian)源，公司主(zhu)要經(jing)營(ying)“正泰(tai)(tai)”牌配電(dian)(dian)(dian)電(dian)(dian)(dian)器(qi)(qi)(qi)、控制電(dian)(dian)(dian)器(qi)(qi)(qi)、終端電(dian)(dian)(dian)器(qi)(qi)(qi)、電(dian)(dian)(dian)源電(dian)(dian)(dian)器(qi)(qi)(qi)、電(dian)(dian)(dian)力電(dian)(dian)(dian)子(zi)、儀器(qi)(qi)(qi)儀表、建(jian)筑電(dian)(dian)(dian)器(qi)(qi)(qi)、高壓電(dian)(dian)(dian)器(qi)(qi)(qi)及成(cheng)套設(she)備。

接觸器類

此類電源切換系統以(yi)接(jie)觸(chu)(chu)器為切換執(zhi)行部(bu)件，切換功能用中(zhong)間繼電器或邏輯(ji)控制(zhi)(zhi)模塊(kuai)組(zu)成(cheng)二(er)次(ci)回路(lu)完成(cheng)控制(zhi)(zhi)功能，PC雙(shuang)電源供(gong)應(ying)商，一般為非(fei)標產品(pin)，缺(que)點是主回路(lu)接(jie)觸(chu)(chu)器工作(zuo)需要二(er)次(ci)回路(lu)長期通電，容易產生溫升發熱、觸(chu)(chu)點粘(zhan)結、線圈燒毀(hui)等故障。因為是非(fei)標產品(pin)，其(qi)組(zu)成(cheng)元器件較(jiao)多，PC雙(shuang)電源報(bao)價，產品(pin)質量受(shou)元器件、制(zhi)(zhi)造工藝制(zhi)(zhi)約，故障率(lv)較(jiao)高，現(xian)已逐漸被(bei)新產品(pin)代替。
